I'm fairly certain that the bars should change out quite easily; I'm more concerned about the shifters and brakes. Currently I have a hybrid 18 speed with cable disc brakes and Shimano Deore XT derailer. I know that these are typically mountain bike parts. I'm eyeing up the Shimano 105 STI dual control shifter/brake. Is this even going to work?
My main reason for wanting the change is after riding the road for quite a few years with flat bars my wrist are starting to take a bit of a beating. I put some bar end on the flat bars to change my grip position, which helped my wrists, but now I feel my grip is too wide.
If pictures would help i can try to upload some tonight, any advice would help.
